Features
The AIR-SA20PK is an “S-AIR” compatible packaged product that consists of one S-AIR
main unit AIR-SA15Ti and two S-AIR sub units AIR-SA15R.
Connecting the S-AIR main unit (hereafter called “Main unit”) with the S-AIR sub
units (hereafter called “Sub units”) using “S-AIR” technology, you can use each unit in a
remote location.
For example, you can install the sub units, one in the study room and the other in the
bedroom, and then install the main unit in the living room. You can then listen to the
music from the main unit located in the living room by controlling the sub units.
You can also connect the main unit to an optional AV system (such as a TV), and on this
optional AV system you can enjoy audio, video and photo contents of an iPod which is
connected to the main unit.

S-AIR (Sony Audio Interactive Radio frequency)
Recent times have seen the rapid spread of DVD media, Digital Broadcasting, and
other high-quality media.
To ensure that the subtle nuances of these high-quality media are transmitted with
no deterioration, Sony has developed a technology called “S-AIR” for the radio
transmission of digital audio signals with no compression, and has incorporated this
technology into the EZW-RT10/EZW-RT10A.
This technology transfers digital audio signals with no compression using the 2.4 GHz
band range of ISM band (Industrial, Scientific, and Medical band), such as wireless
LANs and Bluetooth applications.

Identifying the main unit with
a specific sub unit (Pairing
operation)
It is easy to set the same S-AIR ID for the
main unit and the sub units to establish
the connection.
However, if a neighbor has an S-AIR
main unit with the same S-AIR ID as
your S-AIR main unit, you may be able
to hear the audio transmitted from your
neighbor’s S-AIR main unit on your
system. To prevent this, you can identify
the main unit with a specific sub unit by
performing the pairing operation.

1 Place the sub unit to be paired
near the main unit.
Pair the main unit with the sub units
one at a time.
2 Check that the power of the
main unit and the sub unit are
turned on.
3 Check that the S-AIR ID of the
main unit is the same as the SAIR ID of the sub unit.
4 Press the PAIRING buttons on
the rear panel of the main unit
and the sub unit using a pointed
object.
When pairing is performed, the
displays on both the main unit and
the sub unit change as follows:
“PAIRING”  “COMPLETE”
To cancel pairing
Change the S-AIR IDs of the main unit
and the sub unit to different S-AIR IDs.
To stop the pairing operation midway
Press the PAIRING button again.
To pair the main unit with multiple
sub units
Repeat steps 1 through 4.
If the S-AIR connection is
unstable
Since the S-AIR product uses radio waves
that share the same frequency (2.4 GHz)
as other wireless systems, such as wireless
LAN or Bluetooth devices, interference
or poor transmission may result if you
use other wireless systems near the main
unit and/or the sub units.
In this case, the connection may be
improved by changing the RF CHANGE
(Radio Frequency Change) setting on the
main unit.
1 Press SYSTEM MENU on the unit.
2 Press TUNING/SELECT +/ on
the unit repeatedly until “RF
CHG” appears, then press ENTER

Precautions
Notes on use of the S-AIR product
As the S-AIR product transmits sound
by radio waves, sound may skip when
radio waves are obstructed. This is a
characteristic of radio waves and is not
a malfunction.
As the S-AIR product transmits
sound by radio waves, equipment that
generates electromagnetic energy, such
as a microwave oven, may interfere
with sound transmission.
As the S-AIR product uses the radio
waves that share the same frequency as
other wireless systems, such as wireless
LAN or Bluetooth devices, interference
or poor transmission may result. In
this case, take the following steps:
Do not install the S-AIR product
near other wireless systems.
Do not use the S-AIR product and
the other wireless systems at the same
time.
The transmission distance differs
depending on the usage environment.
Find a location where transmission
between the main unit and the sub
units is most effective, and install the
main unit and the sub units there.
On the speaker system*
This speaker system is not magnetically
shielded, and the picture on nearby TV
sets may become magnetically distorted.
In this situation, turn off the TV, wait
about 15 to 30 minutes, and turn it back
on.
If there is no improvement, move the
unit far away from the TV.
* The sub units only.
Cleaning the cabinet
Clean the cabinet with a soft dry cloth.
Do not use any type of abrasive pad,
scouring powder, or solvent, such as
thinner, benzine, or alcohol.
Others
On safety
Completely disconnect the power
supply cord and the power cord from
the wall socket (mains) if the main unit
and the sub units are not going to be
used for an extended period of time.
When unplugging the units, always
grip the plug. Never pull the cord itself.
Should any solid object or liquid get
into the main unit and the sub units,
unplug the units, and have them
checked by qualified personnel before
operating them again.
The power supply cord and the power
cord can be changed only by a qualified
service facility.
On placement
Do not place the main unit and the
sub units in an inclined position or
in locations that are extremely hot,
cold, dusty, dirty, or humid or lacking
adequate ventilation, or subject to
vibration, direct sunlight or a bright
light.
Be careful when placing the main unit
and the sub units on surfaces that have
been specially treated (for example,
with wax, oil, polish) as staining or
discoloration of the surface may result.
On heat buildup
Heat buildup on the main unit and the
sub units during operation is normal
and is not cause for alarm.
Do not touch the cabinet if it has been
used continuously at a high volume
because the cabinet may have become
hot.*
Do not obstruct the ventilation holes.*
* The sub units only.
